  1. A presentation on SMART DUST Presented by:-
  2. Smart Dust – An Introduction  Miniaturization  MEMS – Micro-electro-mechanical Systems.  Radio transmitters and receivers  Tiny Computerized Sensors  Single units known as MOTES
  3. Smart Dust History  Conceived in 1998 by Dr. Kris Pister of University of California – Berkeley  Funded by DARPA – Defense Advanced Research Project Agency  Powering Issue
  4. Smart Dust Overview  Merger of Computers, Mechanics and electrics with miniaturization technology  Its core is small, low power Computer  This Computer monitors the sensors embedded in the same chip  Uses RF link for communicating and transmitting necessary information along with MEMS embedded in the same chip
  5. Components & Specifications  A small, low power computer, with a operating system called Tiny OS.  Sensors  Battery  Reflectors and transmitters for reflecting the laser beams  And other as per requirements of the dust
  6. Smart Dust Working  Motes are run by Microcontrollers  Microcontrollers takes the reading from the sensors, processes it and stores it  It uses optical receiver to receive the messages from other motes  It uses corner cube retro reflector or “Laser” to transmit sensor data to other motes
  7. Smart Dust working  The batteries are the basic powering devices in the motes  The motes are in sleep mode most of the time with a little consumption of a few micro amps  Counters and timers periodically trigger on the sensors which take the readings, micro- controller transmits them, stores them and the mode again goes to the sleep mode
  8. Applications  Military  Smart Office Spaces  Environmental Applications  Diagnosis of Human Problems  Security Purposes  Conservation of resources  And many more………………..
  9. Smart Military Operations  Can be used to sense enemy movements  They can help to collect battlefield intelligence  Can be proved as a weapon against bioterrorism  Can be proved as brilliant spies
  10. Smart Environment  Can be used as seismic sensors  Can be sewn in clothes to sense the working environment and change in it, so that the user can get better off it  Can be used to identify the pollutants present in the environment  Can make our life better by sensing these elements
  11. Smart Medication  Can assist a Handicap person about the paths  Can assist in detecting and destroying tumor cells in the body  Can help to identify Various type of diseases for whom the definitions are not yet given by defining them in the tiny OS and matching them
  12. AD-HOC networks  Smart dust can be used to form Ad-hoc networks, which can use radio link to transmit data  These ad-hoc networks can be used in various fields where normal links are not possible  Ad- hoc networks can be much cheaper than usual modes of certain applications
  13. Future Goal  In march 2003, this mote named Spec was made in which all the contents of a mote were fitted in less than 5 Sq mm, in less than a dollar. We can imagine motes to be as small as Dust Particles.
  14. Future Goals  Weather/seismological monitoring  Internal spacecraft monitoring  Land/space comm. networks  Chemical/biological sensors  Weapons stockpile monitoring  Defense-related sensor networks
  15. Conclusion  Smart dust is the power of pc in a dust particle.  Extent of miniaturization  Can help us to lead a better life, in our own beautiful environment
